IQ Tests MeasureIQ Tests Measure
IQ as a construct Monocultural ideas of what IQ means as a
construct. Cultural impacted ideas of speeded tests,
Working Memory Techniques, Q&A methods, etc.
Cultural expectations of the community that created the test
Performance of individuals in the normative groups that are represented in the sample.

BIAS DefiniedBIAS Definied
Systematic differences in performance b/w groups not attributed to the ability being measured.
Bias occurs when tests are given to diverse individuals who are not comparable in background, experiences, and exposure that that of the individuals comprising the norm group.

Developmental nature of test Items
Developmental nature of test Items
Test are Developmental/ incremental (easy to Hard) Learning English may have begun at a
different developmental point for ELL. Students may juggle knowledge b/w L1 and
l2 instead of being able to know just one language well.
Students may have received fewer overall hours of exposure to English language than native English speaker.

Test ValidityTest Validity
If a test is biased, whatever the reason, you may be testing something other than the construct that you want to examine.
IQ and Achievement tests should measure IQ and Achievement and NOT English Language proficiency!!!

Group Assignment: representative normsGroup Assignment:
representative norms What are some of the problems with
using tests that are normed based on the census data? American Indian or Alaska Native; Asian;
Black or African American; Native Hawaiian or Other Pacific Islander; White; Some Other Race; Hispanic or Latino
What are some ways that these problems can be overcome?

Normative StratificationNormative Stratification
Stratification in the norm using race does not equate to stratification based on culture.
There are currently no tests that stratify based on acculturation.
There are currently no tests that stratify based on amount of time exposed to English.

Verbal/Nonverbal BiasVerbal/Nonverbal Bias
Bias in nonverbal tests may occur if the instructions are in English only
Nonverbal tests not normed using stratified acculturation and Language are still biased.
Bias in many tests are revealed more in the verbal tasks than in the nonverbal ones. May be due to learning styles of demonstration,
sample, doing instead of socratic method May be due to L1 and L2 differences

Bilingual Verbal Ability Test (BVAT)
Bilingual Verbal Ability Test (BVAT)
Comprised of 3 WJ-R Cog subtests Picture Vocabulary Oral Vocabulary Verbal Analogies
first conducted in English, any items missed are re-administered in L1
All correct answers L1 or L2 are counted toward total score.

Bilingual Assessment using BCA-Bil and GIA-Bil
Bilingual Assessment using BCA-Bil and GIA-Bil
One attempt to change the scores on the WJ-III (eng or Spa) into a bilingual measure (instead of 2 monolingual measures) includes the creation of the BCA-Bil and the GIA-Bil.
These scores attempt to combine the benefits of BVAT and WJ-III (Eng or Spa), but have serious psychometric issues
Also, since the same samples are used, this problem is not fixed.

This table only addresses through 7th grade. Thought is that if starting school in US after
7th grade, then student should have CALP in l1 by then
Background information on previous education is CRUCIAL!
Consider assessment based on CALP and background information.
